What to do when polypharmacy is identified on a claim

Managing complex medication regimens on injury claims

Published: 3 April 2026 | Updated: 3 April 2026

The polypharmacy problem

A claimant walks into their pharmacy with a list of 12 medications. Some target pain, some target inflammation, some address medication side effects, some are for pre-existing conditions that have become destabilised by the injury. The pharmacist looks at the regimen and sees risks: drug interactions, duplicated therapy, medications that could be removed, side effects compounding each other. Your medication bill is substantial. The claimant reports feeling unwell but isn't clear why. The question becomes: is this regimen working, or are we managing a problem through medication complexity rather than addressing the underlying issue?

Polypharmacy (concurrent use of multiple medications) is common on injury claims, particularly long-term ones. It's not inherently problematic if each medication serves a clear purpose and the regimen is optimised. But often, polypharmacy reflects uncoordinated prescribing, reactive addition of medications rather than strategic optimisation, and incomplete review of whether each medication is still necessary.

Your role is to identify polypharmacy, assess whether it's justified, and coordinate optimisation when necessary. The goal is never to deny medications the claimant needs. It's to ensure the regimen is efficient and working toward injury recovery, not simply accumulating medications indefinitely.

Step 1: Identify polypharmacy on the claim

The first step seems simple: count the medications. But polypharmacy definition varies. Most definitions consider five or more concurrent medications as significant polypharmacy. However, even fewer medications can be problematic if they're mismatched or inappropriate. Focus on both quantity and quality.

You're looking for patterns that suggest the regimen needs optimisation. Examples: three different pain medications, none at optimal dose; an antidepressant added for pain rather than mood; multiple agents for the same symptom; medications continued despite lack of documented benefit.

Step 2: Assess whether polypharmacy is justified

Not all polypharmacy requires intervention. Some claimants legitimately need multiple medications. Your assessment should address whether the medications serve distinct purposes and are optimally selected and dosed:

A regimen that's clearly documented, strategically developed, at optimised doses, and producing benefit is justified polypharmacy. A regimen that's accumulated reactively, contains overlapping agents at suboptimal doses, and lacks clear evidence of benefit is problematic polypharmacy that needs intervention.

Step 3: Refer for pharmacy review

If polypharmacy appears problematic, refer for a medication review. Provide the pharmacist with specific context: "This claimant is on X medications for a Y injury. I'm concerned that the regimen has become complex and I'm not seeing clear evidence of benefit. Can you assess whether the medications are appropriate, identify any optimisation opportunities, and recommend whether any medications could be removed or consolidated?"

A good pharmacy review will address:

• Whether each medication is still indicated
• Whether medications are at appropriate doses
• Whether any medications duplicate each other's effects
• Whether any drug interactions create risk
• Whether side effects from one medication are being addressed by adding another rather than changing the first medication
• Recommendations for optimisation, consolidation, or deprescribing

Step 4: Develop an optimisation strategy

Based on the pharmacy review, work with the treating doctor to develop an optimisation strategy. This might involve:

• Consolidating medications (e.g. switching from two pain medications to one optimised agent)
• Removing medications that aren't producing benefit
• Deprescribing medications whose indication has been resolved
• Addressing side effects by changing the medication causing them rather than adding more medications
• Clarifying the active treatment goals and ensuring medications support those goals

Work collaboratively with the treating doctor. Frame the conversation as optimisation, not restriction. Say: "The claimant is on quite a heavy regimen. I've had a pharmacist review it and they've identified some opportunities for optimisation. Let's talk about whether we can simplify the regimen to improve outcomes and reduce side effects."

Step 5: Implement optimisation gradually

Don't change everything at once. Implement optimisation changes sequentially so you can monitor the impact of each change. A typical approach:

1. Identify the lowest-priority medication (minimal documented benefit, contributes to side effects, or duplicates another agent)
2. Plan to reduce or stop it over a specified timeframe
3. Monitor outcomes: does the claimant's condition improve, stay stable, or worsen?
4. If outcomes are stable or improve, the medication was successfully deprescribed
5. Move to the next optimisation priority

Document this process clearly so the claimant and treating team understand what's happening and why. Transparency prevents resistance and builds buy-in for optimisation.

Monitoring polypharmacy outcomes

Once a polypharmacy case is identified, establish monitoring to ensure the regimen remains appropriate:

This monitoring helps you identify regimen drift (accumulation of medications over time without corresponding benefit) and ensures polypharmacy cases don't become unnecessarily complex.

Common polypharmacy patterns and responses

Pattern A: Multiple agents for a single condition

The claimant is on three different pain medications, none at optimal dose. This typically reflects reactive prescribing where agents are added when satisfaction isn't achieved, rather than optimising individual agents. Response: consolidate to one optimised pain agent; deprescribe the others; if pain control is inadequate, add specific adjuncts only after the primary agent is optimised.

Pattern B: Medications targeting side effects of other medications

The claimant is on an opioid, a laxative for opioid-induced constipation, and an antiemetic for opioid-induced nausea. The opioid dose is suboptimal. Response: optimise the opioid dose appropriately; potentially reduce opioid so constipation and nausea reduce; reassess whether adjunct medications are still needed once the primary agent is optimised.

Pattern C: Medications added but never removed

The claimant was on a trial of an antidepressant for pain that didn't help; rather than stopping it, a different pain medication was added. Now they're on both. Response: deprescribe the unsuccessful agent; ensure any new medications are adding benefit, not just accumulating.

Pattern D: Pre-existing medications not reviewed

The claimant's regimen contains all their injury-related medications plus all their pre-existing chronic disease medications. The total burden is high and interaction risk is significant. Response: clarify medication scope (which are covered as injury-related, which are the claimant's pre-existing responsibility); focus optimisation on injury-related medications; provide the claimant with clear information about their pre-existing medications so they can manage these with their own doctor.

Summary: Your action plan

When you identify polypharmacy, assess whether it's justified by clear indication, therapeutic dosing, and documented benefit. If polypharmacy appears problematic, refer for pharmacy review. Develop an optimisation strategy with the treating doctor. Implement changes gradually and monitor outcomes. Establish ongoing monitoring to prevent uncontrolled regimen complexity. The goal is efficient, purposeful medication regimens that support injury recovery, not medication accumulation without corresponding benefit.

Well-managed polypharmacy can be appropriate. Unmanaged polypharmacy is a liability. Take the time to optimise complex regimens early; it pays dividends in better outcomes and reduced long-term claim cost.
